table top androtatable tray.

The device forming my invention may be used to advantage for many purposes. For the purpose of illustration only I have shown and will describe the invention in connection with the usual hospital bedside table, Where this use has proven highly advantageous both to the patients and the attendants in hospitals. g

The object of the invention is to provide a Combination table top and rotatable tray, the size of which can be standardized and the structure of which is so made to facilitate 5 attachment and detachment from an ordinary table. y I Another object of the invention is to provide a combination table top and rotatable tray which allows the user to merely rotate the tray in order to bring any object thereon into close proximity and eliminate the necessity of reaching for the object. This is especially advantageous to patients in hos- The invention relates to a combination pitals who must not exert themselves, and in cases of operations where reaching would be harmful and painful. I

Another object of the invention is to provide a combination table top and rotatable tray which is simple, yet eflicient in design, and which can be kept clean and sanitary.

Still another objectof the invention is to provide a combination table top and rotatable tray which is of lasting quality and cheap to manufacture.

With these and other objects and advantages in mind, attention is called to the drawings, in which J Figure 1 is a view in elevation of myin- 4b vention, showing its attachment to the ordinary table used generally in hospitals.

Figure 2 is a plan view of my invention, Figure 3 is an enlarged sectional view of my invention taken on the line 33 of Figure 2 showing the mounting'of the rollers in the table top, rotatable tray, and guard rail.

Figure 4 is a plan view of a modified form of my invention showing a circular base with I rotatable tray mounted thereon.

Figure 5 is an enlarged sectional view of my invention taken on the 1ine.55 of Figure .4, and v v Figure 6 is anenlarged sectional View of another modified form of my invention, showing a circular base and a rotatable tray thereon.

Referring specifically to the drawings, as pecially Figures 1, 2 and 3, in which like numbers indicate'like parts, 1 are thelegs ofthe ordinary standard hospital bedside table, and 2 is the table portion. The table top 3, in the form here chosen for illustration, is of rectangular shape, having flanges 4 extending downwardly on each side which fit snugly on the table portion2. It'is ob vious that the table top 3; may bejof any shape desired to facili tateattachment to variously shaped tables and may be fastened thereon either by means of the wedging action of the flanges or any other suitable methods known to those skilled in the art. 7

. Provided at correct intervals in the table top are apertures having ears 5 struck downwardly. Rollers 6 are placed in said apertures so that portions thereof protrude above the surface of the tabletop 3' and are rotatably held therein by means of bolts 7extending between the ears 5. n

A rotatable tray 8 is provided on its outer edge with a hollow annular flange comprising an upwardly and slightly outwardly extending portion 9 from which extends a flat portion 10 from whichextends a downwardly and slightly outwardly extending portion 11. The strip of sound deadening material 12 is provided on the underside of the flat portion 10. r I i When the rotatable tray and table top are assembled for operation, thehollow annular flange formed by the portions 9, 10 and 11 of the tray provides a runway for the rollers, and it will be noted that the tray 8 and the portion 11 have just suflicient space above the table top to allow free rotation of the tray. A guard rail 13 extends substantially around three-fourths of the circumference of the tray, and is-supported by any suitable.

means, such as brackets li secured to the 7 table top. The guard rail prevents possible 9 thereto, ear 18 which is struck up and which interference with'the rotation of the tray by too close proximity of other objects set upon the free portion of the table top.

A modified form of my invention, shown in Figures 4 and 5, comprises a circular base which in structure is quite similar to the rotatable tray. In this form, the guard rail brackets 14 extend inwardly between the base and the rotatable tray and are'secured to the former in any suitable manner. The brackets form the bearings for the rollers. The circular base and tray may be attached to a round or otherwise shaped table or may simply be positioned upon a table wherever convenient to the user.

Referring to Figure 6 there will beseen a portion of another form' of the rotatable tray comprising a circular base member 16 having on its edge a flange 17 and adjacent together with the flange 17 forms supports for the rollers. A bolt 19 extends between the cars 18 and the flange 17 to form a bearing member for said roller. Four rollers of similar construction and arrangement are used inthis complete tray. The modification here shown is useful simply as a tray with a rotatable top portion which can be placed upon the users lap or in hospitals upon vthe patients bed.

The shape of the rotatable tray member in all of the 'forms shown is such that articles placed thereon will not slide ofl', due to the flange, and any spilled liquid will be prevented from flowing off the tray.

In order to thoroughly clean and keep the device sanitary, it is simply necessary'to lift the rotatable tray from the base, and such actionexposes all operating parts.

The material used in constructing my device may be light metal such as aluminum,

although it is obvious that many otherspecific metals and other types of materials can be used.

It is understood that there are various other modifications of my invention which are within'the spirit and scope of the appended claims.

I claim r 1. In a device of the class described, a base member having depending flanges, rollers mounted on said base members, and a tray member having an annular flange rotatably supported by said rollers, said annular flange cooperating with said rollers to guide said tray member in rotation. I i

2. In a device of the class described, a metallic base member having slot-like apertures out therein, rollers mounted in said apertures, and a tray member entirely supported and mounted for rotation on said rollers.

3. In a device of the class described, a base member having aperturestherein, ears positioned at and below two sides of said apertures, rollers supported between said ears and the tray member mounted for rotation on said rollers.

4. In a device of the class described,a base member having apertures therein, ears struck downwardly from the sides of said apertures, bolts extending between said ears, rollers mounted on said bolts, and a tray member mounted for rotation on said rollers.

5; In a device of the class described,a base member provided with depending flanges and having apertures therein, ears struck downwardly from the sides of said apertures, rollers'supported between said ears,'and a tray member having an annular flange rotatably supported" by said rollers, said annular flange cooperating with said rollers to guide said tray member in rotation.

6. In a device of the class described,a

base .member provided with depending flanges and having apertures therein, ears:

struck downwardly from the sides of said apertures, rollers supported between said ears, a traymember having an annular flange rotatably supported by said rollers,a guard rail mounted on said base member and positioned above and encircling said tray mem- I ber, said annular flange cooperating with said rollers to guide said tray member in rotation. I

' 7 In a rotatable tray, a base member having an annular flange, a tray member having said base and tray members to rotatably support said tray member. 7

9. In a rotatabletray, a base member having an, annular flange, a tray member having an annular flange, brackets positioned between said base and tray members and attaohed to said base member, a guard rail held by said brackets, rollers between and within the annular flanges of said base and tray members to rotatably support said tray member, said brackets forming bearings for 1 said rollers. I

10. In a rotatable tray, a base member having an upstanding flange, ears struck up adjacent said flange, a tray member having an annular flange, and means between said base member and said tray member, to rotatably support said tray member.

11. In a rotatable tray, a base member hava ing an upstanding flange, ears struck up ad jacent said flange, a tray member having an annular flange, and rollers held between said upstanding flange and said ears and cooperating with said annular flange, to rotatably support said tray member.

12. In a deviceof the class described, a
